Case Study: ExpressVPN achieves faster, lighter web performance with imgix

ExpressVPN cuts image file size by 70%, bandwidth consumption by 30%, and page weight by 10% using imgix

ExpressVPN, one of the world’s largest VPN service providers, needed to replace legacy infrastructure and improve web performance as competition grew and its sites had to load quickly across devices and languages. The company turned to imgix for image optimization and delivery to support faster pages, better user experience, and a smoother workflow for engineering and marketing.

Using imgix, ExpressVPN implemented automatic srcset generation, the Rendering API, and secure image URLs, with quick setup and seamless integration into its new tech stack. The results were significant: image file size dropped by 70%, bandwidth use fell by 30%, and page weight was reduced by 10%, while the marketing team gained easier image management and A/B testing through Asset Manager.
